[Pk A180 6'. R5772 BY vm METHOD OF AND MEANS FOR INDICATING THE POSITION OF A CUP IN A GOLF COURSE GREEN BACKGROUND OF THE INVENTION It is customary in the maintenance of golf courses that the cup in the green of each hole is periodically removed to preserve the area of the green adjacent the cup which would experience severe wear from continued activity if the cup remained in the same location.

Thus, the green is protected against the need for substantial, time consuming and expensive repairs.

Placement of the cup at different locations in the green poses a problem to players who are unaware of a change in location. The location of the cup is generally indicated to the golfer by a pin which .is placed in the cup and carries a flag at its upper end. While such a flag is visible at some'substantial distance, the golfer may not be able to determine at such distance the relationship of the flag to the green, including the traps surrounding the green. The green may beoddly shaped,

contoured and trapped, so that the golfer will play his shot so as to place the ball in the most advantageous position on the green. If, however, the player is unable to visually determine whether the pin is in the right or left side or forward or rear portion of the green he may not play the hole to greatest advantage, notwithstanding the fact that the player may be experienced with the particular green. If the golfer is not familiar with the course, the problem is more aggravated, since the player is not only unable to visually determine the placement of the pin on the green, but, also, he may be unable to visualize the topography of the green, i.e., how it slopes, where the traps are, even though the players score card may show the shape of the green.

THE PRIOR ART It is the practice in some golf courses to provide in the clubhouse a pictorial representation of the various greens and to place a marker roughly at the location of the cup at each green. While such devices have some value to experienced and inexperienced players, the devices do not satisfy the need for visually indicating to either class of playerthe topography of the green while the player is at the tee or at some other location remote from the green. Neither does such a device enable a player to visualize the best approach to the particular green as he is about to make a shot.

SUMMARY OF THE INVENTION The present invention enables a golf player to visually analyze the topography of a selected green in a golf course hole, and to play the hole to best advantage, as may be dictated by the placement of the cups at various locations on the green and by the hazards surrounding the green.

- More particularly, the invention provides a model of the green which is constructed in accordance with the topography of the green, including traps, shrubs, and other hazards adjacent to the green, and which is located at the tee, to provide a visual indication to the player of the green form and arrangement, as well as to provide a visual indication of the location of the cup in the green. Thus, if the player is unfamiliar with the green, on the one hand, or while being familiar with the green, is unaware that the cup has been re-located, on

the other hand, the player is better able to determine the proper or the preferred manner of playing the hole.

In accomplishing the foregoing, the green of the golf course is physically reproduced, including surrounding hazards, in the form of a relief, scale model, which according to typical practice in the production of models of the general type involved may be at one scale in a horizontal plane, but at a lesser scale in a vertical plane, to visually emphasize the depth of trap and variation in grade or slope of the green or the surrounding apron and adjacent region.

To obtain the desired degree of authenticity or accuracy in the model green, a selected green may be surveyed, includingthe surrounding area, or if the course was constructed according to architectural drawings which are current, such drawings may be employed as a guide to production of the model of the green. To practice the invention, however, a facility is provided for establishing a reference point on the green of the course from which measurements may be taken to determine the relative placement of the cup in the green. Such measurements are taken each time the cup is moved, and a cup marker on the model, say, a representation of a marker pin and flag, is placed in the same relative location on the model green.

The model is housed in a protective and supporting enclosure. The enclosure must be opened periodically to enable re-location of the cup marker on the model green, and accordingly, the top of the enclosure is transparent to expose the modelgreen to view and openable to allow re-location of the cup marker.

This invention possesses many other advantages, and has other purposes which may be made more clearly apparent from a consideration of a manner of performing same. One manner of performing the invention is illustrated in the drawing accompanying and forming a part of the present specification. The method of use thereof will now be described in detail for the purpose of illustrating the principles of the invention; but it is to be understood that such detailed description is not to be taken in a limiting sense, since the scope of the invention is best defined by the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevation of means according to the invention for indicating the position of a cup in the golf course green;

FIG. 2 is an enlarged top plan, with a portion of the transparent cover broken away, to expose the model green; and

, FIG. 3 is a section as taken on the line 3--3 of FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT As seen in the drawings, an enclosure 10 is provided, including a base wall 1 l which is suitably attached as by fasteners 12 to a support flange 13 provided at the top of a post 14 adapted to be installed in a golf tee 15 in an upright position, preferably adjacent to the location at which the golfer addresses the ball for his tee shot.

The enclosure 10 may be of any desired configuration but is illustrated as being substantially square having upstanding sidewalls 16 at the top of which is a closure 17 of transparent material, such as a transparent acrylic, having a down-tumed edge flange 18 which extends about the sidewalls 16. Suitable sealing means, such as a gasket 19, may be provided to prevent the entry of foreign matter into the enclosure. Illustratively, the closure 17 is provided at one side with a hinge 20 suitably affixed to the sidewall of the enclosure 10 and at the opposing side, the closure and the sidewalls 16 have means for locking the closure in a closed position, such as, for example, a hasp 21 adapted to be locked in place by a lock 22 to prevent unauthorized entry into the enclosure 10.

Within the enclosure 10 is a model M of the green of a particular hole of a golf course. The model M includes a representation of the green 30 as well as the surrounding green apron 31. The model of the green also includes the various hazards which may exist, such as in the case of the illustrated green, a number of I peripheral sand traps 32, 33 and 34, as well as peripheral shrubbery indicated at 35 and 36.' In its preferred form, the model M is constructed in relief, say, from papier mache, clay or other moldable material, so that not only is the general plan of the green represented for the player, but, also, as best seen in FIG. 3, the player may visually determine the grade or slope of the green and its surrounding area.

Within the green proper, it isprovided with crossed lines or markings 37 and 38 having graduations 39 and 40, respectively, which are preferably numbered to designate the distance from the reference point 41 at which the markings 37 and 38 cross and the periphery of the green proper. In the construction of the model M, it will be apparent that the various surfaces and hazards may be appropriately colored to more or less realistically correspond to the actual green of the golf course.

A marker 42 is adapted to be placed on the green 30 to indicate the location of the cup in the green of the golf course. Since the usual marker for the cup in the green of the golf course is a pin having a flag, the market 42 is preferably of that same type, the pin being supported on a base 43 for supporting the marker in an upright position. Means are provided for retaining the marker 42 in a selected position. For example, such means may comprise providing iron filings as indicated at 44 in the surface of the green 30 and employing a magnet as the disc 43, so that when the marker 42 is placed at a selected location on the green 30, it cannot be displaced by shock forces applied to the structure.

in the practice of the invention, either when the green of the golf course is being surveyed or at any time that it is desired to install the device illustrated in FIGS. 1-3, the green in the golf course is measured in crossed directions to establish a reference point on the golf course green. These measurements are taken on lines established for future reference, say, by the driving of markers into the green in opposed relation to establish the lines of future measurements to be made when the position of the cup is changed. These opposed points are represented at 37a, 37b and 38a, 38b on the model green 30. It is immaterial whether these points be located on the golf course green with reference to the model green or located on the model green with reference to the golf course green. The significant point is that, for future reference, a greenkeeper who periodically changes the location of the cup is enabled to ake measurements from a refer nce int on the gol course green corresponding to t e re erencc point 41 on the model green 30 to provide coordinates enabling the placement of the marker 42 on the model green 30 in a location substantially representative of the location of the cup in the golf course green. These coordinates would be established by measurements of the golf course green each time the cup is moved, and therefore, the markers driven into the golf course green, at the points corresponding to the points 37a, 37b and 38a, 38b on the model green, may provide hooks or the like to enable connecting a surveyors measuring tapes to the books, so that the reference point is provided at the intersection of two of the tapes stretched across the green of the golf course.

From the foregoing, it will be apparent that a golfer at the tee of the hole of thegolf course provided with a model of the green as herein shown and described is readilly able to visualize not only the general layout of the green of the hole which he is about to play but also the player is certain of the relationship of the usual marker pin in the cup in the green of the golf course relative to the rest of the green including the surrounding hazards. Thus, the player is better able to endeavor to place his shot either at the desired location on the green or at the preferred approach to the green. It may be desired, moreover, in the case of a particular hole of a golf course where the green is not viewable from the tee, that adjacent to the model of the green there may be further representation of the entire hole, including, for example, a dog leg which prevents the green from being visible from the tee. Under these circumstances, the invention enables the player to better visualize the best manner of playing his shot out of the dog leg into alignment with the green.
